Viewers will see Debbie becoming tearful as she speaks with Lewis Bloor and Carol Wright about a recent row she had with her daughter over Lydia's on-off boyfriend Arg.
On Sunday night's show, Lydia alluded to the fact Arg's continuous involvement in her family had been creating tension. He's her ex-boyfriend, while Debbie has always seen him as a son.
Arg has just returned to TOWIE following a period of suspension over his excessive partying. After spending Christmas in rehab, he has now tidied up his act and is back on the show.
It's not all good news, however, as tonight we'll see Lydia once again worrying that Arg is coming between her family.
She's spoken before about how she'll always support and love him but admits it can be difficult as it causes rows among her close-knit family.
Arg has credited Lydia for being the reason why he went to rehab and changed his behaviour but has also said she's now the reason he can get upset.
In scenes aired on Sunday night, he told her: "After everything that happened, I want to say sorry Lydia. I've put you through so much. It's my fault, but at the moment, me having contact with you is a bit negative on my life. I think it's a good idea that you do your thing and I do my thing. I'm going to take a big step back."
TOWIE airs Wednesdays and Sundays at 10pm on ITVBe.
